Using two iPhones - any pitfalls?

I'm toying with the idea of buying a second-hand 6S+ once the prices come down even further next month, so I can switch off with my SE (and use a big screen when I feel like it). For folks who regularly switch off between two iPhones... any big "cons" to this arrangement (beyond the minor hassle of swapping the SIM card)?

I assume my Health data (distance walked / steps taken) won't sync between the two devices, and so I'll have big "gaps" in my timeline in each device (and won't have accurate "Daily Average" measurements). Would an Apple Watch keep an accurate tally?

Beyond that... I think my podcast app (Overcast) and password manager (pwSafe) will sync/update data with multiple devices via iCloud, as it seems to work with my iPad. My calendar/contacts sync through Google, so no issue there. Notes and Reminders sync via iCloud, which seems to work ok with the iPad (though I'll have to remember to launch Reminders when I switch phones, as the sync doesn't happen in the background).

Had both a Plus and a regular for a month, along with a 5S. Only the regular got used. Compact and easier to maintain. If you have one for business and one for personal, it makes sense, since the current lineup only supports a single sim. With dual sim, I would pick one...

I have an iPhone 5, an iPhone 6s+ and an iPad Air 2. The iPad and the 6s+ both have their own SIMs and the 5 is only active on WiFi.

I have contacts and calendars synced through Google and multiple email accounts. I only keep all of my account on the 6s+. iMessages syncs across all devices and since my iPad is cellular I can also push SMS and calls to it.

I use three contacts for iMessage (2 emails, 1 phone number) for all three devices, but set each device up to send as it's own contact so I know which device sent what.

All my music is in Google Play so I can stream it from all three devices. Video and photos (I want to keep) I use my 6s+ for. None of the data on the iPad or the 5 is important.

Well, I'd still like it carry it around in my pocket, and use for calls and stuff...

(Which reminds me of another thing that I assume won't sync: call logs.)

My iPad Air 2 and iPhone 6s call logs sync with each other. I'm assuming its because I have WiFi calling enabled on both devices to be used with the same number. So if you are using a second number on the second iPhone, then it might not sync. There could be a workaround with iCloud/WiFi calling settings.

I own and use both a 6s and SE. Right now, my SE is the daily driver while I have iOS 10 PB installed on my 6s. I used to pair and un-pair my AW with both phones, but that was a hassle, so I just keep it paired to my 6s. The only time both phone's are on is when I want to go from using my SE to 6s. Typically I just pop the SIM in, turn the other phone off and I'm good to go.

I use Apple Music, so any playlists that I save (not offline) on my SE are still there on my 6s when I want to use it. iCloud is great for when I enter a new contact since when I connect to the internet on my other device, it will sync up.

So definitely go for it. It's not much of pain to do (otherwise myself and others would not do it).
